Final Fantasy 5  

Obtain Mimic Profession 
To get the profession of Mimic in Final Fantasy 5, make sure you have the 
submarine first. Then, try to find a tower underwater, and enter it. Go all the 
way to the first floor (you have 8 minutes to do this) and answer "no" to Gogo's 
question (it helps a if you have the "dash" ability or have someone as a thief). 
When you fight Gogo, don't do anything. You will win in about a minute or so. 
Then, Gogo will give you the job "Mimic".
